Ozempic and GLP-1 Body Skin Changes: What's Happening and What Helps

Updated September 2026

GLP-1 medications like Ozempic, Wegovy, Mounjaro and Zepbound don't damage skin directly, but the fast weight loss they can bring often shows up on the butt, hips and thighs as looser, less elastic skin, dryness, stretch marks and sometimes breakouts. What helps most is protecting muscle with enough protein and strength training, moisturizing daily, and being realistic: skin care can improve how skin looks and feels, but it can't tighten significant loose skin.

This is general information, not medical advice. Talk to your prescriber before changing your medication, diet or exercise, and see a dermatologist about skin changes that worry you.

What happens to your skin on a GLP-1?

According to Cleveland Clinic, some people lose as much as 25% of their body weight on GLP-1 medications, and it's the speed and amount of weight loss, not the drug itself, that drives most appearance changes (Cleveland Clinic). On the butt, hips and thighs, people notice:

1. Looser, crepey skin. Fat that used to fill out the area shrinks faster than skin adjusts, and some muscle goes too. The flatter, sagging result is sometimes called "Ozempic butt."
2. Dry skin. The AAD lists dryness among reported skin effects, linked to hormonal changes and drinking less (AAD).
3. Breakouts. The AAD also notes some people get acne from hormonal fluctuations.
4. Stretch marks. Rapid weight change is a known cause (AAD).
5. Friction rashes. Loose, folding skin can rub and get irritated.

Why does muscle loss matter for how your butt looks?

When you lose weight, you lose some lean mass along with fat. A 2026 review reported that in real-world data, fat-free mass made up roughly 25–30% of the weight lost on GLP-1 medications (Metabolites review). Your glutes shape a lot of your butt, so losing muscle there adds to the deflated look, and it's the part you have the most control over.

What helps skin during GLP-1 weight loss?

1. Protect muscle with protein and strength training

It's not a skin care step, but it matters most. The same review describes eating around 1.2–1.5 g of protein per kg of body weight a day during active weight loss, plus resistance training at least two to three times a week. Appetite suppression can make that hard, so ask your prescriber or a dietitian how to reach your target, especially if you have kidney problems. Glute exercises help the butt specifically.

2. Moisturize every day

For GLP-1-related dryness, the AAD recommends hydrating products with ceramides, applied to your whole body. Use a fragrance-free ceramide cream after showering, and drink enough fluids.

3. Exfoliate gently if skin feels rough

If skin feels rough or flaky, gentle exfoliation 2–3 times a week can help. Becky Booty Scrub exfoliates with finely milled walnut shell and leaves skin feeling smoother and softer. It won't tighten loose skin or fade stretch marks. Skip scrubbing on chafed or irritated folds. For more on softness, see how to make your butt soft.

4. Use retinoids carefully

The AAD notes that prescription tretinoin can make early, still-pink or purple stretch marks less noticeable. But retinoids can irritate skin that's already dry, which the AAD flags for people on GLP-1s. Start slowly, moisturize, and ask a dermatologist what to use, particularly if you're pregnant or planning to be.

5. Protect skin from the sun

The AAD also recommends sun protection. Use a broad-spectrum sunscreen on any exposed skin.

Can you fix loose skin after GLP-1 weight loss?

Honestly: creams and scrubs can make skin look and feel smoother and more hydrated, but they can't tighten significant loose skin. That usually takes in-office procedures or surgery, such as body contouring. For stretch marks, dermatologists use options like lasers, radiofrequency and microdermabrasion. A board-certified dermatologist or plastic surgeon can tell you what's realistic for you.

When should I see a doctor or dermatologist?

See a dermatologist or your prescriber if you notice:

• Painful, severe or scarring acne, or breakouts that don't improve after 6–8 weeks of treatment
• A spreading rash, or an injection-site reaction that doesn't settle
• Red, hot, painful or oozing skin, especially in folds, which may be infected
• Noticeable hair shedding
• Any spot that changes shape, size or color

The bottom line

GLP-1 skin changes are mostly about losing weight quickly. Protect muscle with protein and strength training, moisturize daily, exfoliate gently if skin feels rough, and be cautious with retinoids. Skin care can improve how skin looks and feels, but it can't tighten significant loose skin. For more, read stretch marks on the butt and how to get rid of butt acne.
